Solar Mounting Bolts & Fasteners
Bolts, screws, nuts and washers for PV rails, clamps, brackets and roof attachments. Supply can be matched to drawings by thread, length, head or drive, material and finish.
- T-bolts & rail hardware
- Hex & flange bolts
- Roof screws
- Nuts & washers
- Drawing-based matching
Hardware for common PV mounting interfaces
Final part selection should follow the approved rail, bracket, clamp or roof-attachment detail.
T-Bolts & Hammer-Head Bolts
Used in compatible rail or channel profiles. Head geometry, insertion method and thread must match the receiving slot.
Hex & Flange Bolts
Used for brackets, frames and other joints where the drawing defines hole size, grip length, thread engagement and mating hardware.
Self-Drilling Screws
Used only where the mounting design permits direct fastening to the specified metal substrate. Confirm material thickness and sealing requirements.
Structural & Lag Screws
Used where the approved design calls for a penetrating structural fixing. Diameter, embedment and installation method must follow the system documentation.
Nuts & Locking Hardware
Hex, flange or specified locking arrangements should be matched to the bolt thread, material and joint design.
Flat & Sealing Washers
Washer size and material should suit the joint. For roof penetrations, use the sealing detail specified for the complete attachment assembly.
Information needed to match the hardware
A drawing, BOM or mating-component profile is the clearest starting point for quotation and compatibility review.
- Fastener type and application
- Rail channel, slot, hole or mating-component dimensions
- Thread diameter and pitch, length, head geometry and drive
- Connected material thickness and required thread engagement
- Material, finish, exposure environment and any sealing requirement
- Quantity, matched nuts or washers, packaging and destination
Fields to confirm before production
Values vary by mounting system and project. Use the selected system drawing or installation documentation for the final specification.
| Fastener family | T-bolt or hammer-head bolt, hex or flange bolt, self-drilling screw, structural or lag screw, nut, washer or matched set. |
|---|---|
| Interface | Rail slot or channel, hole diameter, bracket or clamp geometry, connected thickness and available tool access. |
| Thread & length | Diameter, pitch, total length, threaded length and required engagement from the connection drawing. |
| Material | Confirm the specified stainless-steel or carbon-steel grade and the required mechanical property or class for the part. |
| Finish & exposure | Confirm the finish or coating appropriate to the selected material and service environment, including corrosion and sealing requirements where applicable. |
| Installation | Use the exact fastener and mounting-system documentation for torque, embedment, pre-drilling and other installation limits. |
| Supply format | Loose parts or matched sets can be quoted after the BOM, quantity, labeling and packaging requirements are confirmed. |
